Functional Test of Digital Input Positioning
Normally you need a simple controller to set the digital inputs used to select the point table posi-
tion entries, for example a PC, a mini PLC or an HMI control terminal. This chapter explains how
you can perform a thorough check of the functionality of the positioning control functions without
needing to perform the additional work of programming and installing a controller.
Fig. 4-19 shows a test installation without an external controller. Note that the FX Simulation Box
used in this setup can set a maximum of 14 digital inputs.
NOTE
The test setup shown above does not use any safety features for the tests (EMG. OFF). You
should thus only use this setup in a controlled test environment where errors cannot cause
any danger for personnel or equipment!
